Chest pain is universally a leading cause of emergency department visits. Technological
advancements have led to the development of high-sensitivity troponin assays. The
application, interpretation, and appropriate utilization of their results is still
under investigation. Furthermore, the increased sensitivity of these assays raises
additional challenges such as determination of true myocardial infarction (MI) versus
other causes of myocardial injury, appropriate timing of serial troponin sampling
(i.e., from 1 to 6 hours), and prognostic implications of persistently elevated troponin
levels. This study sought to develop a calculator capable of identifying the probability
of acute MI (AMI) and 30-day outcomes, as well as provide prognostic information on
patients identified as not having a myocardial infarction.
